Dale Irby is a man of admirable consistency. The Dallas, TX teacher wore the same outfit — a brown V-neck sweater over a patterned white leisure shirt — in each of his annual yearbook photos for a whopping 40 years . Even his trusty facial hair remained mostly unchanged throughout his decades-long career. And while this may have all been part of a long-running joke after a young Irby accidentally wore the outfit two years in a row, it brings up an interesting conceit: that of the personal uniform.

While we're all for choice, there's something to be said about a man who sticks to one look and makes it his signature. Just try, for instance, to picture Steve Jobs without his faded Levi's and black mock turtleneck. Sure, the stylistic merits of his choices may be debatable, but the fact that he managed to create an iconic image of himself is indisputable.

And therein lies the power of dress. While peacockery has become increasingly popular in the past decade, there's a case for a simplicity and rigor, for creating a singular image of oneself. Plus, it makes life that much easier: Wearing a personal uniform means one less decision morning decision to make, and god knows we've already got enough of those.

If you're a proud clotheshorse, carry on, fine sir. But for the others out there: Know that looking good doesn't necessitate a constantly evolving wardrobe. Just make sure your clothing fits — always, always make sure it fits — and that you're comfortable and feel like yourself in it. Oh, and don't forget to buy in multiples; you never know when your favorite item will be discontinued. Then, just sit back and watch as your signature look coalesces.
